To all wlaom z't may concern:

Be it known that we, -KAnL Pnmz ZU LtSwENsrEIN and Dr. FRITZ HAUFF,residing at Necka-rgemiind, Germany, and Stuttgart,

Germany, have invented certain new and useful Improvements in Methods ofProduc- Specification of Letters Patent.

ing Nitrogen-Containing Compounds, (forwhichwe have filed an applicationin Gery y 1 15,) of which the following '10 is a specification.

The present invention relates to the utilization of methane or gases ofthe methane -,series in the formation ofcyanids or cyana-- mids.

The methane or the like is highly heated and is thereby dissociated intopure carbon and pure hydrogen.

T he carbon is mixed or briqueted With an alkaline salt, for instance;barium carbonate orother bariuinsalt. I

The hydr gen is burned in atmospheric air and the nitrogen of the airthereby heated without the application of external heat. The resultinmixture is cooled until the steam produced by the combustion isprecipitated-leavin the nitrogen free.

The nitrogen is torced in heated condition nin'rnon or PRODUCINGNITROGEN-commute comromms.
